5.3.4 Camera Calibration
Camera calibration is important for maintaining consistent image quality. Calibrating the cameras
resets the white level and balance, as well as the black level and balance in the scanner. It
performs red, green, blue (RGB) color balance and gain setting, and horizontal light level
correction. The final measurement results in a correction function which levels the brightness
over the complete scan width.
Two white calibration sheets are used for the camera calibration procedure. These sheets are a
part of the camera calibration kit that is included with the scanner. Additional kits can be
purchased from our on-line store at www.bbhscanners.com
or call BBH Sales at 1-800-SCAN-
494. Kits are also available for purchase through BBH Authorized Service Providers (ASPs), and
Authorized Spare Parts Resellers (ASPRs). A list of ASPs and ASPRs is available at
www.bbhscanners.com
.
The Ngenuity scanner’s cameras can be calibrated independently or together; however, BBH
strongly recommends that cameras always be calibrated together. The duration of the calibration
process when calibrating both cameras should take approximately 4-7 minutes.
N
OTE
Before calibrating the camera(s), make sure to clean scanner optics to ensure a successful
calibration with the best possible results (see ”5.3.2
Optics” on page 68).
NOTE
Before calibrating the camera(s), make sure full power is applied to the scanner (not in Sleep
mode) for at least 5 minutes.
Item(s) Needed
• Two, clean camera calibration sheets, free of folds, tears, marks or any other matter that could
cause less than ideal calibration results
To calibrate the cameras, perform the following:
1. Establish communication between the scanner and the NOU (see ”2.2
Ngenuity Operator
Utility” on page 29)
2. Within the NOU, click on one of the Calibrate
links found in the Maintenance section of the
NOU’s Home page
Cameras can be calibrated individually; how-
ever, BBH strongly recommends that both
cameras always be calibrated at the same
time.
